The night after their 6 week birthday the girls finally went into the coop. Every night for 3 weeks I would have to go out and retrieve each and every one of them and put them in. The night after they turned 6 weeks I went out to do the nightly ritual and WOW! they had all gone in and were quietly sleeping all over the floor of the coop. I was so pleased. I wasn't sure if they would ever quit sleeping out in the run. I guess they are growing up!
